• Unicode Emoji 17.0 RGI sequence support and a reproducible generator for the emoji regular expression

Fixed

• Aligned quote, fenced code block, search, italic, hashtag, URL, and link parsing more closely with mfm.js
• Preserved input and continued parsing after invalid or incomplete syntax fallbacks, including unclosed MFM functions
• Supported CRLF and standalone CR newlines consistently across block parsers
• Rejected empty code nodes and invalid mentions while preserving subsequent valid syntax

1.0.1 - 2026-01-21

The reason for the PUB POINTS being 150 on pub.dev was due to exceeding the 180-character limit in the description. I shortened part of the explanation to fit within the base character count. There are no changes to the library's functionality with this update.

1.0.0 - 2026-01-21

Added

• I rewrote the parsing process from scratch using Dart and petitparser, based on mfm-js. At this stage, the basic parsing functionality is complete. I plan to create the rendering process using a different library in the future.
